Optical fibre sensing - where might it lead?

Prof. Brian Culshaw

Strathclyde Engineering Faculty, Glasgow, UK

Optical fibre sensing has been with us for almost half a century during which the technology has made important, if specialised, contributions to measurement techniques. The aim of this talk will be to assess these contributions and thereafter to suggest possible avenues for the future combining guided wave optical sensing with emerging societal needs and photonics technologies.

Optical Communications: a key technology for telecommunication networks. History, present and possible future

Prof. Michel Joindot

Laboratoire FOTON, CNRS Université de Rennes 1, France

The first transmission systems using optical fibres appeared in the telecommunication networks thirty years ago, after an intensive research effort period to solve basic issues like the attenuation of fibres or the achievement of reliable semi-conductor lasers. Since that date, performances of optical communications systems have increased dramatically in terms of capacity as well as transmission quality and reliability, especially with the advent of Wavelength Division Multiplexing and optical amplification: optical fibre became the unique transmission medium to be used in the high capacity long distance networks, transforming very deeply their architecture and enabling the transmission of Internet data over cables throughout continents and oceans. As far as access networks are concerned, fibre allows bringing to the customers a bit rate which could not be achieved before, opening the way to new broadband services.

This presentation will sweep the history of optical communications, starting form the basic research of the seventies and the first systems in the eighties up to the last developments of 2015. The major technical milestones, like WDM and optical amplification, will be put in evidence and the deep change in network structure related to the introduction of optical systems will be explained.

After this historical presentation, the second part will be devoted to the place of optical communication in the networks today and finally we will try to draw some evolutions for the future.

The laser: a bright solution looking for a problem

Prof. Orazio Svelto

Polytechnic Institute of Milan, Milan, Italy

After more than 50 years since its invention, the laser continues to create around itself a mixed atmosphere of curiosity and wonder. Curiosity mostly comes from the fact that new lasers are still being invented and new, quite fascinating, applications developed. Wonder essentially comes from the pervasive character of the laser: there is, in fact, no field of science and technology which has not been influenced, often fundamentally, by this revolutionary invention. To celebrate the international year of light, this talk will review some early beginning of laser developments and applications, with anecdotes and curiosities coming from the author’s personal experience.
